Double Glazed Windows Repairs
If your double-glazed windows are hard to open or have mist between the panes, this could be an indication of seals that are not working properly. It is worth getting them fixed if this is the situation.
This is a cheaper option than replacing windows. This type repair requires specialized tools and equipment, so it's recommended to leave this work to an expert.
Seals that have been damaged
The window seals can be worn down over time and allow argon gas or Krypton to escape between the panes of double or triple-paned windows. A damaged seal allows outside air to enter and the argon gas that is used to insulate your home to escape. Both of these are bad for energy efficiency.
Window seals can be damaged by extremes in humidity, temperature and pressure. These changes cause your window glass to expand and shrink, which puts a lot of pressure on the seals over time. This can happen when your children or pets accidentally scratch your windows.

If your window seal is damaged, it's a good idea to have the problem investigated by a professional as quickly as you can. If you put off the repair for too long, the argon or krypton gas may disappear completely, and this could significantly diminish the insulation properties of your window.
Another sign that your seal isn't working is noticing fogginess between your window panes. While you can resolve this yourself by defogging, the best way is to hire a professional to visit and repair your window.
A technician will take off the seal on the window, clean the glass and replace the seal after windows are sealed. The technician will take apart the sash, if necessary then reassemble it, and replace the IGU (insulated unit) when necessary. Then, they'll insert argon or krypton into the void between the panes and reseal around the IGU to ensure a watertight seal. This process isn't a DIY job however, you can find several kits that claim to help homeowners with this. The reviews for these products aren't always positive however, and we would recommend leaving this job to experts.
Condensation
Condensation is a potential issue with double-glazed. This is especially the case in older homes. It occurs when the air within a house is warmer than the glass and has a higher dew point meaning that moisture can form inside. It is more likely to occur during night or in the early morning hours, when temperatures are at their lowest.
Fortunately, condensation in double glazed windows is easily repaired and usually does not require replacement of the entire window or door. The'spacer bar' that is located between the two glass panes in the majority of double glazing is filled with desiccant, which is extremely absorbent and absorbs any moisture that comes into the void of air. If this spacer bar is saturated with moisture, it may be leaking into the frame of the window where condensation develops.
